∠1 = 14

∠2 = 76

Step-by-step explanation:

To find the measure of both, first find out the total angle's degrees. It is a right angle which means it is 90°

Angle 1 and 2 are complementary angles, which tells us that ∠1 + ∠2 = 90°

∠1 = x - 5

∠2 = 4x

You should substitute ∠1 with x - 5 and ∠2 with 4x in the equation ∠1 + ∠2 = 90°

(x - 5) + (4x) = 90°

You would solve this like a normal equation. Start by simplifying the left side.

5x - 5 = 90° now add 5 on both sides

5x = 95 now divide 5 on both sides

x = 19

Now that you know what x is equal to, substitute x for 19

∠1 = (19) - 5

∠2 = 4(19)

So now we know that ∠1 = 14 and ∠2 = 76

If you add 14 and 76, it equals 90
